You know, when Walkedu raced the v1.47 proceded carr with his v2.0 car people attributed the huge gain walkedu had on the v1.47 car mostly to the version 2, where I argued that the huge lead walkedu had was more due to his exhaust, DPs, and FMIC.
I would absolutely love to see the people (driver72) (sflgator) that said that the huge gain was attributed to v2.0 come into this thread and say that the huge lead Bimmerman had on sflgator is due to his small modification (exhaust, catless dps). After all they did say themselves that these "small" modifications had no HUGE effect on walkedu's v2.0 car stepping on the v1.47 car.

I think most of us are interested in understanding what all of these mods are doing and equal comparisons of tuners.

Unless someone wants to dyno their car after every mod, and take mods off to install them in different orders, we may never know what these mods produce individually, or how we should prioritize our upgrades.
